With the increase in electric vehicles (EVs) on the road, charging stations are becoming common. However, have you ever wondered how the chargers work and what components they require to function? Chillers are one of the essential components that help regulate the temperature of the charging station and ensure smooth operations. In a previous post, I spoke of the importance of having chillers on electrical vehicle chargers:
This post will discuss the different types of chillers used by EV chargers and their specific requirements. Electric Car Charging Points
Liquid-Cooled Chillers: Water-cooled chillers are widely used in EV charging applications requiring large power quantities. They utilize water as the coolant and provide efficient cooling at high ambient temperatures. Water-cooled chillers come in two types: shell and tube and plate heat exchanger. Shell and tube usually require more space, making them ideal for outdoor installations, whereas plate heat exchangers have a smaller footprint, making them perfect for indoor installations.
Glycol-cooled chillers use a mixture of water and glycol to remove heat from the battery in the charger. They are designed to work in extreme temperatures and are more efficient than air-cooled chillers. However, glycol-cooled chillers have a higher upfront cost than air-cooled chillers and require more maintenance than water-cooled chillers.
Air-Cooled Chillers: Air-cooled chillers use air as the coolant and are commonly used for smaller EV charging stations. They are ideal for applications with limited space and no water availability. Air-cooled chillers come in different types, like scroll, screw, or reciprocating, that vary in terms of their size, efficiency, and…
